How do i determine whether it is an ignition problem or fuel problem when my starter turns the engine but doesnt start?

Remove a spark plug (any one will do), and lay it somewhere on the engine where you or a buddy can see it (not near that puddle of gasoline, though, thank you very much). Crank the engine. If you see a nice bright spark (believe me, you won't miss it if it's there) then you have a fuel delivery problem. If you see no spark, you have an ignition problem. Be sure to replace the spark plug after this test.

Your 2001 cabrio wont start it has a new battery why wont it start?
You need to determine whether your problem is a "no crank" problem, or a "no start" problem. To determine if it is a "no crank" problem, you will need to make two jumper wires. The first jumper wire should be about 6"-8" long, clips on either end, about 18g wire. disconnect smaller gage wire wire on the starter solenoid and jumper it with your jumper wire. Turn the ignition key on and then using another heavy gage (about 10 gage) wire, go directly from the positive terminal of the battery to the terminal on the starter where the battery wire connects. The engine should crank over. If it does not, replace the starter. If it does crank over, then you don't have a "no crank" problem, you have a "no start" problem, in which case this may be an issue with the alarm system. I goit lucky in that my problem was the starter, and not the alarm system. I performed the trouble shooting that I described above to determine that it was a bad starter. I replaced the starter, and all is well!
Why does the starter make a spinning noise and cranks the engine but engine wont start?
In a situation like this you must determine whether lack of fuel or lack of spark is preventing your motor from running. To test this disconnect the air intake behind the mass air flow sensor. Have someone try to start the vehicle while you spray starter fluid ( available at parts stores ) into the intake manifold. If the vehicle starts you have a fuel problem. If it does not start you have a spark ( ignition electrical ) problem.
1996 dodge intrepid wont start?
If the 1996 Dodge Intrepid will not start, there might be an issue with the battery or the starter. This could also be a problem with the solenoid or the fuel gauge or fuel pump. The problem and the fix will vary depending on whether the car is completely dead or is cranking when the ignition is turned.

How do you make a problem in slope of an area?
The slope of an area will determine the problem that you will be able to make, whether it is an even or a steep slope.
Which stage in the process of gathering network symptoms involves determining if the problem is more likely a hardware or software configuration problem?
You determine symptoms through observation and operation. You then diagnose where the problem occurs in the network, and determine whether the problem is excessive data (i.e. software) or component failure
How do you find the problem if your Chrysler Sebring's 20v ignition fuse keeps blowing out?
I had the same problem. Everytime I would turn the ignition past Accesory to the On position the 20A fuse would pop. I went through 15 or so fuses. I could get it to start every now and then, so one time it started I drove it up to Sears Auto and they diagnosed the Battery as having a bad cell. Replaced the battery and haven't pop a fuse since then. Popping the 20A ignition fuse....have your battery tested and probably replaced! check the starter too if battery is good I had this problem as well. It turned out to be the starter. It occurs when you move to "start" and the starter fails to engage. Whether this was simply a bad solenoid, or something else in the starter, I can't say for sure. In short, if the engine didn't immediately turn, the fuse would blow in about 2 seconds. I got around it for quite a while by being very careful to not hold the switch in start unless I detected the engine turning over. Eventually the starter ws relaced and all is well.

You determine ownership
How do you determine whether a rock is a rhyolite or an andesite?
The composition of the rock will determine whether it is a rhyolite or an andesite.
Will the pick up coil in a distributor keep you from hearing the fuel pump run a couple of seconds when you turn the ignition on in a 1993 Taurus 3.0 you replaced the ECM and the ignition coil?
No. The fuel pump should run for 2 seconds when the key is cycled from off to run, regardless of whether there is a problem in the ignition system or not.
How do you know if a starter solenoid is bad?
bypass it by connecting the battery cable directly to the starter motor. remember the solenoid is just a low voltage switch which exists so that high current cables do not have to be run to the starter system. wheni you turn the ignition key it should activate an electro-magnet in the solenoid which causes a metal bar to connect the battery power to the starter motor. so just bypass it to prove whether it works or not.
What to do when engine is locked?
I'd suggest reposting your question with more detail. It's difficult to determine whether your engine has seized due to lack of oil, whether your alarm system has locked out the starter, something in between or none of the above. Maybe you can't get the hood open?
